Specification of Letters Patent.

Patented Apr. 2, 19th.

Application filed December 30, 1916. Serial No. 139,860.

To all whom it may concern:

Be it known that I, RICHARD MICHAEL O'r'ro TILLMANN, subject of the German Emperor, residing at Hamburg, in the German Empire, have invented certain new and useful Improvements in Machines for Treating (lasks, Barrels, and the like, of which the following is a specification.

The present invention refers to amachine for treating casks, barrels and the like and more particularly to a pitching machine. This machine differs from known machines designed for similar purposes inasmuch as all mechanisms are operated from a single driving shaft and in a novel manner, and that the devices for placing or transposing the casks are rotated about a single axis, that is to say about thedriving shaft. Moreover the invention refers to the special arrangement and construction of certain devices used in the machine. This invention will be .used with particular advantage in pitching machines and particularly for this reason that the operating devices driven by a single shaft not only combine the device for removing the pitch with a device for supplying a coatlng of pitch, but

. also enable a more convenient couphng or two or more of such devices in a simple manner, a common. shaft being provided for all these devices.

In the pitching machines known heretofore the means for revolving the devices for removing the pitch and for revolving. the

casks are very deficient and require. to be improved upon, since in these known machines the driving mechanisms are very com- .plicated on account of the intermittent and reciprocating movement of the devices for removing the pitch and. for transposing the casks, it being impossible to adjust the depitching nozzles in placing and transposing the casks to the necessary exactness by the means employed heretofore.

According to the present invention the common driving shaft causes an intermittent movement of the depitching device andan' uninterrupted rotation of the device for transposing the casks and eventually also the device for placing the casks, while in the known pitching machines, in which the rotation of the pitching device is intermittent, also the movement of the transposing device is carried on intermittently. Theuninterrupted rotation of the device for transposing'the .casks together with the 111- termittent rotation of the depitchmg de vice according to the present invention is favorable for the new arrangement and construction of the driving mechanisms to a great extent. The machine itself is more simple and allows of a great saving of power.

In the drawings by way of example pitching machines are shown, to which the invention is applied.

Figure 1 is an elevation and Fig. 2 a plan ofthe machine.

Fig. 3 shows a pitching machine in elevation, working without a depitching device and Fig. 4 is a plan of the last named machine.

Fig. .3 is a sectional elevation of a depitching device and Fig. 6 shows a device for placing casks, partly in section. 1

In the machine shown in Figs. 1 and 2 the driving shaft 1 is arranged} between a rotary depitching apparatus A, having a central hot air producer and a pitching apparatus B. A prolongation 2 of the driving shaft extends, at an angle to the shaft 1,

between the depitching apparatus and a mounted on the shaft section 2 and is adapted to lift a cask from a peg 6 of the placing device C and place it onto anozzle 9 on a cask carrying arm 8 of the depitching apparatus A and a transposing or lifting off device t is mounted on the shaft 1 to lift a cask from a nozzle 9 and place it on a nozzle 7 of the pitching apparatus 13.

Each cask carrying arm 8 has two parallel projecting arms provided with anti-friction rollers 17. In case the arms 8 are not brought to a stop at the proper point with relation to the peg 6, one of said rollers will lie in the path of movement of the transposing device 5 and before the latter has reached the'position for depositing the barrel on the arm 8, the transposing device, by engaging either of the rollers 17, will minutely adjust the arm 8 by shifting it laterally to bring the nozzle 9 into position to project into the bung-hole 0f the barrel.

These transposing devices each' consist of two parallel arms fixed near one end on and revolving withthe shaft 1 -2, and pivotally mounted. on the inside of each arm near the free end. thereof is a cask supporting piece 4, 5, respectively. lhe upper ends of these pieces are notched as shown to form V- shaped seats for the cylindrical casks. To maintain the seats horizontal during the revolution of the free ends of the arms around the shaft, a train of three gears 4 (as shown in dotted lines, Fig. 3) is provided on each arm. The inner gear is fixed on the shaft 1 and the outer gear fixed to the seat piece so that, as the shaft rotates, the seat piece is maintained in a horizontal position through the medium of the central gear.

The driving shaft 1 besides carrying the transposing or lifting off device 4 and on its prolongation 2 the cask placing device 5 carries also the sprocket wheels 10 for operating the pitching nozzle 7 and the cask rolling device 11 respectively (Figs. 3 and 4). Said shaft also carries a cam or lifting arm 12 for moving the cask lifting device, hereinafter described, which facilitates the running off of the melted pitch and a crank arm 13 is fixed to said shaft for driving the depitching device. Finally the driving shaft 1 carries an arm 14 for moving the device which discharges the pitched casks, and two arms 15 and 16, which govern the feeding of the pitch.

As may be gathered from the above, the driving shaft is made in two parts. The intermediate pinion 3, which drives the shaft prolongation 2, gears with two conical wheels and also drives the main shaft 1, so that both parts of the shafting are driven directly. By these means the shaft proper 1 is partly relieved and the use of driving means ro-' tated with a great speed, such as electric motor, is made possible.

The mechanism for rolling the cask and for operating the pitching device is omitted from Figs. 1 and 2 for the sake of clearness and is shown in Fig. 3. Said mechanism comprising a shaft 19 located beneath the shaft 1 and having pivotally mounted thereon a bell crank lever the arm 18 of which is arran ed to be engaged by the arm 14 on shaft 1. The other arm 21 of said bell-crank lever is connected by a rod 22 to a crank arm 22 fixed to a rock shaft 23 which carries a series of lifting arms 23.

These arms extend beyond the pitching nozzle 7 on each side thereof and when the bell crank lever 18-21 is rocked by the arm 14, the lifting arms 23 are raised, lifting a cask from the nozzle 7 and causing it to roll onto the rolling machine 11.

The double armed levers 24 24 and 25 25 are rotatably mounted 011 the shaft 19. When the driving shaft 1 rotates, the arm 15 engages the short arm 24 of the lever 24 and the arm 16'engages the short arm 25 of the lever 25. A counterweight 24" connected with the lever 24 acts in opposition to the movement of the lever by the arm 15. The lever 25 is connected by the rod 26 with a lever 20 attached to the spindle 27 of the cook or valve 29 adapted to feed pitch from the pan 28 to the pitching nozzle 7. To the spindle 27 is fixed a second lever 30 which projects in the opposite direction to the lever 20 and has a rod 31 loosely connected thereto, the free end of which rod rests on a movable stop 32. This stop is connected by a rod 32 with a rock shaft 33 adapted to be actuated by a lever 33, which is so fixed on the shaft 33 in proximity to the nozzle 7 that said lever will be depressed, when a cask is seated over the nozzle, and the shaft rocked, raising the rod and stop. Only when.

the stop 32 is in this raised position is the free end of the rod 31 within reach of the lever 24, which is then enabled to catch hold of the rod 31 by a notch arranged in this lever. The loose end of the rod 31 can be made to work together with the lever 30.

As soon as a cask is placed on the pitching device the arm 15 engages the short arm 24 of the lever 24 and rotates the latter toward the rod 31 which being raised into its higher position is caught hold of and opens in its further rotation the cook 29, so that pitch enters the nozzle 7 and is squirted into the cask. When thereupon the arm 16 rotates by the lever 25 the cook 29 will be closed. The lever 24., which is no longer engaged by the arm 15, is returned in the meantime by the counterweight into its former position thus releasing the rod 31-. When now the arm 15 is lifted the pitched cask is removed from the pitching device by aid of the bell crank lever 18, 21 and the lifting device 23, f

the stop 32 is returned into its lower position, and the rod 31 resting on the same is brought out of reach of the arm 24.

By the arrangement of the rod 31 governed by the cask the discharge of the pitch is avoided when no cask is placed on the pitching device and the driving shaft 1, and

the parts connected therewith are further operated. I

The depitching device, that is to say the device for removing the pitch is rotated interruptedly from the shaft 1 by the crank 13 with a slow alternately increasing and decreasing speed; thus a quiet motion is arrived at and the requisite power being considerably reduced. For this purpose the driving members consist of a crank 13 and a rod 34 connected therewith. The latter is connected with a rack segment or a rack 35 geared with a toothed wheel 36, the shaft of which is so connected with the shaft 39 by a ratchet wheel 38 and a pawl 38, that the shaft 39 is rotated only in one direction by the shaft 37 rotating in either direction. On the shaft 39 a conical wheel 40 is mounted which gears with a toothed rim 41 connected with the depitching device so that the latter is intermittently rotated in one direction in such intervals as will correspond to the distance between two consecutive depitching nozzles 9. Since the crank 13 forms an obtuse angle with the rod 3st at the beginning and at the end of the reciprocating movement of the rack 35 it will cause a slowly increasing and slowly decreasing movement of the rack 35., and therefore also the depitching device will move at the beginning and at the end slowly.

The caskraising device driven by the cam arn'r 12 consists of a cask support 42 arranged diametrically opposite the pitching device, which support is moved upward by pairs of arms 4-3 attached to a bracket and forming parallelograms, which move laterally to the cask carrying arms 8 on both sides and lift the cask resting thereon upward. For this purpose the lower pair of arms 4-3 are attached to a shaft carrying a lever let. This lever is connected by a rod 415 with a bell crank lever L5, which itself is connected by a vertical rod 46 with the oscillating lever lG- (Fig.1). This lever is oscillated upwardly by the cam 12 on every revolution of the shaft 1 and consequently the cask support 42 is raised upward to lift the cask from its seat, thus allowing the melted part of the pitch to run out by the bung-hole.

In order to prevent an unnecessary discharge of hot air by the depitehing nozzles 9 when there is no cask over them, there is a closing member, for instance a plunger a7, arranged below each nozzle for cutting off the stream of hot air which member may be operated by hand.

device to the pitching device there is acontrolling lever 49 arranged on the front service of the carrier arms 8 adapted to engage the piston a7 and provided with cont oiling studs as, and on the lifting oif device l there is a controlling cam 50 (Fig. 1) and on the placing device 5 a controlling cam 51 (Fig. In lifting off the cask by the device l the cam 50 has closed the piston 4.7 by one of the studs 4E8 and thnscut off the hot air stream. When thereupon this carrier arm is moved in front of the placing device 5 and the latter has placed: a cask, that is to be pitched on this carrier arm by aid of the cam 51 the piston 47, is again opened by moving down the other stud 48.

Below the piston 47 there is an initial space 52 for unburnt parts of the fuel, grit, sand or the like, thus preventing the latter from contacting with the piston and from entering the depitching nozzle.

The operation of the devices is as follows:

The de Jitching device rotates in the direction of the arrow shown in Fig. 21 from the pitching device to the cask placing device. lVhen the lifting off device 4- is moved from its vertical upper position (Figs. 1 and 3) to the vertical lower position the cask placing device 5 rotates in an opposite direction,

I To allow an automatic. cutting off of the hot 2111St16t111 when the casks are thrown over from the depitching.

that is from the lower position (Fig. 6) to the uppervertical position. In thus moving, the lifting off device 4: places the depitched cask over the pitching nozzle T and the placing device 5 catches hold of a cask to be pitched from the peg 6 of the cask carrier or from any other place, for instance from the bung-hole seeking place. During this time the depitching device is rotated. Thereupon the latter will be brought to rest until the lifting off device 4: again has come to its initial (upper)- position and has caught hold of a cask to be pitched, while the placii ig de-- vice 5 also has come to its initial (lower) position and has placed a cask to be treated on its adjusted carrier arm 8. While the depitehing device is at rest the cask lying on the'lifting or raising device a2, 4.8 will be taken away from it, so as to allow the liquid pitch to better run off. Evidently there is no limitation to the number of cask lifting devices to be driven by the shaft 1 in proper distribution, only one being shown for sake of clea-rness.

The machine shown in the drawing can he used for treating casks or barrels in another manner, for instance for drying, heating or melting other coatings than pitch. The main parts of the machine, part1eularly the lifting ofi' devieeel, the placing device 5 and the mechanisms belonging to these devices and working in connection with the same can also be used in other cask treating machines, for instance barrel washing machines If the machine used is double acting nevertheless only one single driving shaft may be used as is shown in the drawings for operating-all the devices.

As isshown in Figs. 3 and the invention is applicable in connection with pitching de-' vices alone, making use at the same time ol all the new mechanisms and the single driving shaft. In this case it is not absolutely necessary that the cask transposing device rotate uninteriaiptedly, but in certain positions it might come to rest.
